FerroSilicon
Ferroalloys are iron alloys with metals such as silicon, manganese, chromium, molybdenum, etc., which are raw materials used in the metallurgical industry, especially in the production of iron and steel. Ferrosilicon (FeSi) is an alloy of iron and silicon that is principally used in steelmaking for deoxidation and as an alloying component. The main applications of ferroalloys occur in the steelmaking process. They are added to steel to improve properties like strength, ductility, and fatigue or corrosion resistance.
More information
Among ferroalloys, ferrosilicon is the most widely used in the industry. Ferrosilicon is produced in various compounds according to the type of application, but in general, its composition ratio includes 10-90% of silicon and the rest of iron. At the same time, it contains impure elements such as aluminum, calcium, manganese and etc. Ferrosilicon 75% and ferrosilicon 45% are currently the most widely used in industry. Exon Ridge Ferrosilicon can vary from 70 - 75% Silicon based on customer requirements. The table in the next page shows the chemical characteristics of two types of ferrosilicon.
Ferrosilicon application
Deoxidize steel and other ferrous alloys
Manufacture of other ferroalloys
Manufacture of cast iron, ferrosilicon is used for inoculation of the iron to accelerate graphitization
Manufacture of prealloys like magnesium ferrosilicon, used for modification of melted malleable iron.
As an additive to cast irons for controlling the initial content of silicon
In steel melting, casting, mineral processing and melting rod industry
